Review
OBJECTIVE
This study aims to systematically review the management and outcomes of pediatric patients who develop intracranial pseudoaneurysm (IPA) following head trauma or iatrogenic injury.
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature review was performed. Additionally, a retrospective analysis was conducted on pediatric patients who underwent evaluation and endovascular treatment for IPA originating from head trauma or iatrogenic injury at a single institution.
RESULTS
Two hundred twenty-one articles in the original literature search. Fifty-one met inclusion criteria resulting in a total of 87 patients with 88 IPAs including our institution. Patients ranged in age from 0.5 months to 18 years. Parent vessel reconstruction was used as first-line treatment in 43 cases, parent vessel occlusion in 26, and direct aneurysm embolization (DAE) in 19. Intraoperative complications were observed in 3.00% of procedures. Complete aneurysm occlusion was achieved in 89.61% of cases. 85.54% of cases resulted in favorable clinical outcomes. The mortality rate after treatment was 3.61%. The DAE group had higher rates of aneurysm recurrence than other treatment strategies (P = 0.009). Patients with SAH had overall worse outcomes compared to patients who did not (P = 0.024). There were no differences in favorable clinical outcomes (P = 0.274) or complete aneurysm occlusion (P = 0.13) between primary treatment strategies.
CONCLUSIONS
IPAs were successfully obliterated, and favorable neurological outcomes were achieved at a high rate regardless of primary treatment strategy. DAE had a higher rate of recurrence than the other treatment groups. Each described treatment method in our review is safe and viable for the treatment of IPAs in pediatric patients.

BACKGROUND
Popliteal artery pseudoaneurysms are a rare but serious complication following total knee arthroplasty that have been traditionally managed with open surgical repair. Endovascular stenting, while relatively new, offers a promising alternative that is less invasive and may reduce the risk of perioperative complications.
METHODS
A systematic literature review was conducted, and all clinical reports in the English language from inception to July 2022 were identified. References were manually reviewed to identify additional studies. Demographics, procedural techniques, postprocedural complications, and followup data were extracted and analyzed using STATA 14.1. Additionally, we present a case of a patient with a popliteal pseudoaneurysm treated with a covered endovascular stent.
RESULTS
A total of 14 studies (12 case reports, 2 case series; n = 17) were included for review. In all cases, a stent-graft was placed across the popliteal artery lesion. In 5 out of 11 cases, popliteal artery thrombus was present and treated with adjacent modalities (i.e., mechanical thrombectomy, balloon angioplasty, etc.). Procedure success was reported in all cases without perioperative adverse events. Stents remained patent over a median followup of 32 weeks (interquartile range: 36). In all but one case, the patients experienced immediate symptom relief and had an uneventful recovery. For our case, at the 12-month followup the patient was asymptomatic, and ultrasound demonstrated vessel patency.
CONCLUSIONS
Endovascular stenting is a safe and effective treatment for popliteal pseudoaneurysms. Future studies should be aimed at evaluating the long-term outcomes of such minimally invasive techniques.
